We've recently removed all of our Griselinia hedge as it died but have a few questions if anyone can help please. When we took out hedges, we left roots as they're huge and we were told they could cause structural damage to walls. So I'm wondering can we plant new hedges alongside these?
Also, we were looking at planting a variegated privet instead as we've heard it's meant to be very hardy but would be grateful if for advice/views on this hedge before we purchase. I'm concerned about putting in another hedge in case the same thing happens again. We thought of replacing with a wall but prefer a hedge. Many thanks.

The Griselinia would probably have sprouted from the base again. (Around here, they have. Low of -12° & 14° )

Privet is hardy, so it'll survive. A very hard winter may de-leaf it but it'll be OK.

there is a risk that the privet plants might pick up the disease that the Griselinia had either Phythophtora or Armilaria. Privet is more resistant and more tolerant of these diseases and being native is a much better grower in our climate. There are a number of different varieties including silver gold and variegated.

Do your best to improve the soil along the hedgeline with compost, bought or homemade, as the Griselinia will have exhausted the soil. Don't worry too much about the old roots; they'll eventually rot, so if that is going to damage your house (highly unlikely!) there is nothing you can do about it. From working in tree and shrub nurseries, I've found that privets are basically semi-evergreen. They will lose some of the oldest leaves in the winter. You could also think about Euonymous japonica, which does have a variegated form. If you do go for privet, please don't clip it too often. The sprays of white flowers in the summer are gorgeous! Clip them after that.

Thanks so much for all the helpful advice. I'm going to try to remove as much of the old roots as possible and feed the soil with a mix of compost and manure to hopefully revive it a bit. An existing boundary has a mix of variegated privet and griselinia, so I am trying to find something that would complement this (the next task!). Many thanks again.
